I spotted some 3 1/2" form factor drives that I think may be SCSI
drives of the narrow "SCA" persuasion. I noted them mainly because they
have a small looking black plastic connector similar to a centronics
connector, with what appears to be a central male bar with contacts on it.
It rang a bell about the discussion about such connectors in some
Sparcbook laptops.
Though the form factor is totally useless, it would be interesting if
the bus was the same, and one could fab up a cable out of a dead
sparcbook to such a drive. Just thinking.
I have to grab the drives tomorrow and see what they are. No idea at
all about whether they work, but they have been around for a long time.
Also I have a line on a huge amount of recent junk, and am listing it on
epay. It is way too new (except for technically some 2001 dual xeon
dell serverboards).
contact me off line for some quantum high capacity tape drives if
interested. There are 17 to be had, and a deal on them.

If you are saying they are like SCA, but narrower connector.... you've
probably got
fiberchannel drives there.... not SCSI.

Thanks.. The IIc Plus is tomorrow, but I really can't say too much about it.. I am
trying to put together the anniversaries of many computers and probably make a calendar to
keep track.

I used to get them but they stopped.
I want to make an online Calendar of different dates in Computer History and then every
year just pop them up to say "On this date, blah blah blah happened"
Like today Sept 16 the Apple IIc was introduced, so I made a blog entry.
[http://8bitaficionado.com/?p=198]
Then I saw an article that on Sept 16 1988 Jobs left Apple and on Sept 16 1997 he returned
to his CEO position [http://8bitaficionado.com/?p=266].
I want something that I can keep track of all these dates... I have been looking for
online calendar widgets for Wordpress. I am still learning wordpress. I don't even
have a proper about section. I kinda just made something minimal and started posting.

True... But firstly, you could put several related machines on one page.
And secondly, there are plenty of years still to go (we hope :-)), so you
could produce calnedars with a new set of 12 pictures each year.

Please try... I have one that I haven't done much with (I also have a IIc)
My second job (while I was still in High School) was programming the
Apple II+ (along with the C-64). I still have some of my old work
disks (we used Big Mac for our assembler). I need to get those imaged
off - I expect that they can still be read, but I haven't tried in
many years.
If anyone has any stuff for the IIc Plus, even imaged disks, AFAIK, an
older Mac should be able to write out real media for it (800K 3.5",
unlike earlier Apple II models).

If the drives are the usual 3.5" HDD form factor (as you would find in
a modern PC for example) and the connector is SCA-80 (i.e. takes up
75% or so of the rear width of the drive) then it's almost certainly
SCSI and all you need is a cheap (~ ?5) adapter to hook it up to a
SCSI-1 or SCSI-2 chain. If the connector is significantly narrower
(noticeably less than 50% of the width of the drive) then it is SCA-40
and will almost certainly be Fibre Channel. Some Sun boxes apparently
take FC drives and you can make an adapter to hook them up to an HBA
in a PC.
Interestingly I always thought that SCA-80 was a relatively recent
addition to the SCSI fold, but a few months ago I acquired a Seagate(?)
1GB drive with an SCA-80 interface. So it's obviously not as recent
as I thought.

Yep. And Seagate drives will usually have a "-FC" designator (SCA-80
drives have a "-WC", IIRC)

Yes. ISTR machines of the SPARCserver 3000 and 5000 era (c. 1996)
might have been able to take the -FC drives directly, or at least
through an available drive shelf product of the same vintage. Stuff
from the early 1990s was pretty much all parallel SCSI,
either narrow
or wide (I forget exactly how old wide-SCSI is).
Interestingly I always thought that SCA-80 was a
relatively recent
addition to the SCSI fold, but a few months ago I acquired a Seagate(?)
1GB drive with an SCA-80 interface. So it's obviously not as recent

That connector has been around for at least 15 years. I think I saw a
500MB Seagate drive with an SCA connector once, but those weren't
common. There were lots of 1GB and 2GB drives with SCA connectors.
The oldest machine I've personally used that had internal SCA
connectors is a SPARC5.

You're talking about the Enterprise series, which contains models
such as E3000, E3500, E6500, etc. If the second digit is '0', it uses
SCA-80 SCSI. If the second digit is '5', it's a later model which has
native FibreChannel. FibreChannel drives use SCA-40 connectors.
The Exx00 series take the same proc/mem boards, each of which can
carry up to two 64-bit UltraSPARC-II processors and 2GB or (IIRC) 4GB of
memory. The higher-numbered machines (the first 'x' in Exx00) simply
have more slots for those proc/mem boards.
The lower-level members, I'll use the E3500 as an example, are
self-contained machines with internal drive bays. The E3500 can take
four proc/mem modules in the back and has eight FibreChannel drive bays
in the front. The drives mount on standard "spud" brackets as are used
in the much older machines like the Ultra2.
Ex000 machines are pretty old these days, but Ex500 machines hold
their own quite well, especially for server workloads like email and
database stuff. My company still has two of these in production.
Some of the more recent high-end Sun machines have native
FibreChannel as well. Some examples are the Sun Fire 280r and the Sun
V480/V880. My company is running quite a few of the latter, and my
central computer here at home is a V480.
Current high-end Sun machines that support in-cabinet disks are
typically SAS, though most also have FibreChannel.
